FRANQOIS CARR, OF PARIS, FRANCE.

IMPROVED SEAT AND BACK FOR'CHAIRS.

Specification forming part of Letters Patent No. 54,828, dated May 15, 1866.

To all whom t may concern:

Be it known that I, FRANOIs CARR, of Paris, in the Empire of France, have invented a new and useful Improvement in the Manufacture of' Seats and Backs of Chairs, Stools, Settees, Ste. and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in Which Figure 1 represents a side elevation of this invention. Fig. 2 is a plan or top view of the same. Figli is Iavertical section ofthe same.

Similar letters of reference indicate like parts.

This invention consists in the employment .or use of curved strips of sheet-steel in the manufacture `of seats and backs of chairs, stools, settees, &c., the strips which form the seat being fastened at their outer ends to a frame of suitable forni and material, and at their inner ends to a central disk, and the strips which formthe back being curved out Ward at top and bottom and fastened to suitable crossbars extending across theframe of the back. The strips of the seat are strengthened by secondary strips, which are fastened to the frame and to the outer ends of the main strips, and by these means a seat and back vis obtained which is strong, durable, and very convenient.

a ot represent a series of tapering strips cut out of sheet-steel and secured with their inner ends to a central disk,b, from which the same radiates toward the met-al frame c. Said strips are curved, as shown in Figs. l and 3 of the drawings,and the frame c is round, oval, or of any convenient form Vor shape, according to the article of furniture to be made.

One rivet is sufficient at the inner and one at the outer end of each strip, and the rivets at the outer ends also serve to secure the counter-strips e and the brackets f to the frame c.

The counter'stiips e are cut out of sheetsteel, and curved to correspond to the outer ends of the main strips a, and they are fastened under the same, as clearly shown in Fig. 3 of the drawings, so that the same support and strengthen the main strips and prevent them from sagging down.

The object of the bracket f is to prevent the heads of the rivets from Workin g through the thin metal plates.

The strips or springs a', which compose the back of one of my chairs, are curved out at both ends and fastened tothe horizontal rods h, which extend across the frame h of the back. This 'frame consists simply of a rod of iron bent in the proper form and secured to the frame c, as shown.

Inforder to steady the springs a, they may be connected by a crossbar, t, consisting of thin elastic strips of sheet'steel or other suitable material.

By these means a back is formed which readily accommodates itself to the body of the person sitting on the chair, and which is dura ble, easily constructed, iight, and very con-` venient. i

It Will be observed that my chair seat and back is materially different from metal seats and backs as heretofore made. Common sheetiron seats, either solid or open, have little if any elasticity. They are hard, clumsy, and inconvenient, and the saine may be said of metal seats made ot' Wire braided in imitation to cane seats. Metal seats have also been made of spiral springs, and 4they have at least the advantage of being eXible; but `such seats are liable to sag down in a short time, whereby they are rendered inconvenient and useless.

My seats and backs combine strength and durability with neatness and convenience, and they are applicable to articles of 'any description whatever which serve for seats.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The radiating strips c, ot' sheet-steel or other suitable material, iu combination with the central disk, b, and frame c, constructed and operatic g substantially as and for the purpose described.

2. The secondary supportingstrips @,in combination with the radiating strips a and central disk, b, constructed and operating substantially as and for the purpose set forth.

3. The back of a chair or other similar article, composed of C-shaped strips a', of sheet metal or other suitable material, in combination with horizontal rodsh and frame h', constructed and operating substantially as and for the purpose described.
